Louis P. LAWRENCE, OE PAssAIC, NEW JERSEY, AssIGNOR To THE LAW- RENCE RAILWAY BRAKE COMPANY, OE NEW YORK, N. Y.

BRAKE SADDLE AND'SHOE.

SPECIFICATION forming part of Letters Patent No. 372,810, dated November 8, 1887. VApplication led August 15, 1887. Serial No. 246,960. (No model.)

To all whom zit'may concern:

Be it known that I, LOUIS l?. LAWRENCE, of Passaic, in the county of Passaic, State of New Jersey, have invented 'certain new and useful Improvements in Brake Saddles and Shoes, of which the following is a specification.

This invention relates to certain improvements in brake saddles and shoes, and especially to devices for uniting the saddlesv and shoes.

The object of my invention is to unite the .brake saddles and shoes in sucha manner that they can be connected or disconnected very easily and rapidly, and the shoes are held securelyon the saddles, and there is no danger of the shoes dropping off when they become worn on".

The invention consists in the combination, with a brake-saddle and a sidelianged brakeshoe, of a bolt passed transversely through apertures in the saddle and shoe and provided at one end with a pivoted key.

The invention also consists in the construction and combination of vparts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

In the accompanying drawings, Figure l is a face view of the inner side of my improved brake saddle and shoe. Fig. 2 is an outer edge View of the same. Fig. 3 is a longitudinal sectionalelevation of the saine on the line mx, Fig. 2. Fig. 4 is a horizontal sectional view of the same on the line y y, Fig. 2.

Similar letters of reference indicate corresponding parts.

The brake-saddle A is provided with the side lianges, B, which at or near the middle of their length are united by U-shaped walls forming the box C, for receiving a lever or the brake-beam, and onl which the said saddle is `'secured in any well known manner. The brake-shoe D, which is shaped to iin snugly against the curved side of the saddle, is provided with the anges E, which can embrace the flanges of the saddle, the latter being of such size that it can be placed into the shoe.

A square or rectangular bolt, F, is used to fasten the shoe on the saddle, said bolt being passed transversely through apertures a a in 5o flanges E of the shoe and the aperture of the saddle, said aperture in the saddle being formed between the inner side of the box C and the inner surface ofthecurved part of Bhe Saddle. rlhe bolt F has a square or rectangular head, G, and to receive said head the aperture a in that flange of the shoe facing the flange of the wheel is made of sufficient size that the Outer end of said head is flush with the outer side of 6o said flange and cannot come in contact with theflange of the wheel. At the opposite end the bolt is forked, and between the shanks of said fork the key H is pivoted, which, when the bolt is passed through the apertures in the saddle and shoe, hangs vertically and pre- -vents the bolt passing out of the apertures in the saddle and shoe, and thus prevents accidental separating of the saddle and shoe, and also prevents the shoe from dropping off the 7o saddle when the wearing-surface of the said shoe has been worn off entirely. When the shoes are secured on the saddle by means of bolt-s passed through the wearing-surface of the shoe and the corresponding surface of the saddle, the heads of the bolts are worn off with the shoe, and when said heads are worn o entirely the shoes drop off.

When it is desired to disconnect my improved shoe and saddle, the key H is swung 8o up to be in line with the bolt, when the latter can easily be withdrawn.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination,with a brake-saddle and 8 5 a side-flanged brake-shoe embracing the saddle, of a bolt passed transversely through apertures in the saddle and anges of the shoe and a pivoted key on one end of said bolt, substantially as herein shown and described.
